Thesis Work on Post-Fault Recovery Stability of AI Data Center in Weak Grids

Technology, Data & Digital · Software & Web Development · Software Engineering

In short

This thesis work focuses on the post-fault recovery stability of AI data centers in weak grids. The student will analyze how UPS converter dynamics, DC-link behavior, battery support, and protection logic affect system stability after grid faults, aiming to derive a safe post-fault recovery envelope. The position is for one student with a background in energy engineering, power systems, power electronics, or control engineering, requiring familiarity with simulation tools.

Responsibilities

Examine how UPS converter dynamics, DC-link behavior, battery support, and protection logic affect system stability during recovery after grid faults.
Review state of the art in power-electronic-dominated datacenter grid integration and identify gaps in post-fault recovery understanding.
Identify key parameters (grid strength, loading, converter limits, controller tuning, protection settings) that determine safe recovery.
Derive a safe post-fault recovery envelope mapping stable vs. unstable operating regions.

Requirements

Strong energy engineering background.
Strong interest in solving emerging real-world problems.
Background in power systems, power electronics, or control engineering.
Motivation to solve real-world grid integration problems using dynamic modeling and stability analysis.
Familiarity with simulation tools (PSPSCAD, PowerFactory, or MATLAB/Simulink).

Benefits

5 months thesis work (January 2027-June 2027).
30 ECTS credits.
Located at ABB Corporate Research (Västerås).
